带有正则表达式部分的Laravel路由不会作为参数传递

Question

Is there any way I can have a route set up with one regex section that doesn't get passed as a parameter?

For example:

Route::get('{string}/method/{id}', function($id)
{
    return 'only one parameter passed, ID is ' . $id;
});

Specifically I'm routing to a controller and the methods need to be compatible with routes coming from elsewhere, which don't include this first parameter.

The most important thing is that, routes has to be matched according to it's declaration, for example, if you define a route like your example here

Route::get('{string}/method/{id}', function($id)
{
    return 'only one parameter passed, ID is ' . $id;
});

Then the requested url has to be matched with same numbers of parameters including the http method (GET here) and in this case, the route will match only with something like this

httP//example.com/something/method/10

Here the second parameter 10 is not bound to be digits because you didn't make it to be a digit using where(...) so, it could be anything but two parameters must be required.

As an alternative, you may define a missing method in your controller like this (An idea only)

public function missingMethod($args = array())
{
    // $args will contain all parameters
}

This is a special method in Laravel that any controller may contain it and whenever a non-existing method will be called in that controller, then this missingMethod would be called and all the parameters will be passed to it's $args parameter as an array, so if you have two parameters in the url and calling method is missing in the controller then you may get those parameters within this method scope, something like [param1, param2] and from this method you may call your desired method depending on the count of params .

So, if you just point the route's action to this controller which has the missing method then from the missingMethod you may call another method using different parameters according to your other method.

Also check PHP Overloading and call_user_func_array to get the real idea of missingMethod .
